Fix "http.createClient is deprecated. Use `http.request` instead."
Prevent 400/404 errors

* Without content-length being set for GET requests would
  respond with 400 - Bad Request "Can't pipeline to HTTP/1.0"
* With hostname option set request were not always reaching
  ws.audioscrobbler.com. Setting host has proved to be more
  reliable.
Bump version number and add xhochy as a contributor.
Only add MBID to requestParams if present as it will cause problems
when creating the request signature
Add latest version details, new contributor and make contributors more visible.
Treat undefined and null parameters as blank in signatures.
Remove content-length for GET requests.

Partial revert of 693f893. Content-Length was required because
the data was accidentally being sent in the body of GET requests.
This should only be done on POST.
Bump version number -> 0.8.3
